Geographic patterns in plant-pollinator mutualistic networks [PDF]

open access: yes, 2002
. Recent reviews of plant–pollinator mutualistic networks showed that gen- eralization is a common pattern in this type of interaction. Here we examine the ecological correlates of generalization patterns in plant–pollinator networks, especially how ...

Multiple environmental controls explain global patterns in soil animal communities [PDF]

open access: yes, 2020
Soil animals play important roles in ecosystem functioning and stability, but the environmental controls on their communities are not fully understood. In this study, we compiled a dataset of soil animal communities for which the abundance and body mass ...

Highland barley grain and soil surveys reveal the widespread deficiency of dietary selenium intake of Tibetan adults living along Yalung Zangpo River

open access: yesFrontiers in Sustainable Food Systems, 2022
ObjectiveIn order to assess selenium (Se) flux through the soil-plant-human chain in Tibet plateau and explore the reason why local Tibetan adult residents from large scale agricultural production areas in Tibet lacked daily Se intake.MethodsA total of ...

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]

open access: yes, 2008
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

open access: yes, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

The woodrat gut microbiota as an experimental system for understanding microbial metabolism of dietary toxins

open access: yesFrontiers in Microbiology, 2016
The microbial communities inhabiting the alimentary tracts of mammals, particularly those of herbivores, are estimated to be one of the densest microbial reservoirs on Earth.

Ruminal microbiota–host interaction and its effect on nutrient metabolism

open access: yesAnimal Nutrition, 2021
Rumen microbiota has a close and intensive interaction with the ruminants. Microbiota residing in the rumen digests and ferments plant organic matters into nutrients that are subsequently utilized by the host, making ruminants a unique group of animals ...

Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]

open access: yes, 2019
Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been

Effects of large herbivores on grassland arthropod diversity [PDF]

open access: yes, 2015
Both arthropods and large grazing herbivores are important components and drivers of biodiversity in grassland ecosystems, but a synthesis of how arthropod diversity is affected by large herbivores has been largely missing. To fill this gap, we conducted

Heavy metal hyper accumulation potential of local flora from polluted areas of Delhi

open access: yesEnvironment Conservation Journal
Phytoremediation is a cost-effective in-situ technique that exploits plant physiology for environmental remediation. Using local flora for phytoremediation has the advantage of successful revegetation and prevents leaching of the pollutants, such as ...
